COVER OR FILE FOR RECEIPTS, 86C.

SPECIFICATION forming part of Letters Patent No. 584,285, dated June 8, 1897'. Application filed October l, 1896. lSerial No. 607,559. (No model.)

To all whom, t may con/cern:

Be it known that we, PHILIP HANC, IIL- LIAM BOHMERT, and Louis ZnLvrN, citizens of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Covers or Files for Receipts and other Matter, of which the following is a specification.

The object of this invention is to provide means for the filing of such matter, for eX- amplc, as orders or blanks, receipts, shipping slips, and the like and for enabling such matter to be kept or filed in book form and permanently preserved, if seen fit, in condition for convenient reference; and the invention resides in the novel features of construction set forth in the following specification and claim and illustrated in the annexed drawings, in which- Figure 1 is a side elevation of a file sec tioned along :c x, Fig. 2. Fig. 2 is a rear elevation sectioned along y y, Fig. 1.

The file comprises covers 1 and 2. The cover 1 maybe for convenience styled the front or top cover and cover 2 the end or bottom7 cover. Each cover is shown -hinged or flexibly connected or jointed to a strip or back portion 3 and 4, so that the covers can open and shut or swing on the strips. rlhe covers and strips can be made of suitable material, as pasteboard, boards, or the like, and covered or not, as seen fit.

The strip 4lis shown provided with av guide or strips 5. The strip 3 is shown perforated at 6 for the passage of or to allow strip 3, with cover 1 ,to move along the guide 5. This cover 1 or its strip 3 has a clamp or fastening by which after cover 1 has been suitably adjusted such cover can be secured at the desired distance from cover 2. The clamp or fastening is shown formed by a bow or arched spring 7. This spring is movably seated 0n cover 1, and a screw or stem 11 rises from the cover 1 and is provided with a nut 12. When the spring is sufficiently flattened or compressed by screw 11 12, the guide 5 is clamped or held to hold the cover 1 against motion or slipping.

nut 12 being removed and the cover 1 removed or slipped off the guide or strips the material or leaves to be filed are slipped or threaded onto such strips 5, after which the cover 1 and nut 12 are replaced and the latter suitably tightened to secure the cover 1.

The guide 5 is shown as being flexible. Such iieXible guide can be readily formed from a cord of suitable thickness. A wound wire--as, for example, a piece of an electric conductor with insulating covering or other accessible strip of flexible material-can be made to answer.

The spring 7 is shown held by nut 12 and engages or abuts its ends with the guide 5. Such spring 7 is shown with its ends lying between lips formed by bending or forming a metallic strip or strips 13 14 13, as seen.. The base part 14 or lips 13 14 are secured to cover 1 or strip 3, and said lips are suitably perforated, as at S, to correspond to the perforations 6 for the passage or run of guide 5. Then the spring 7 is tightened or iiatte'ned, the guide 5 is clamped or held or fixed in the perforated lips or parts 13 14.

- In practice it has been found that the flexi- -ble guide or strips have an advantage, for the reason that after the ijle is filled and the file in book form is complete it would at times be difficult to open the les so as to refer readily and quickly to the matter written on the sheets nearest the guides 5 if such guides were rigid.

By the use of the flexible strips the file when complete in book form will curve or yieldl with the weight of the paper inclosed in the file, thus assuming the form of an ordinary book when open and enabling the user of the file to refer to the inner edge portions of the paper or matter inclosed in the file. The importance of this improvement is readily seen when it is known that these les are used largely for writin g figures naming quantities and the like.

What we claim as new, and desire to secure by Letters Patent, is

A file comprising covers, one of the covers The operation of the device is simple. The

being provided with strips or bands forming a guide, and another cover being perforated to receive and move along the guide, lips secured to and perforated correspondingly with said cover, a clamping-spring made to enter between the lips for engaging' J[-he guide, and an actuating-screw for the spring Subsiam tially as described.

In testimony whereof We have hereunto set our hands in the presence of two subscribing 1o witnesses.
